Dear Mr. Beuhler:

By letter dated May 28, 2004, BP Exploration (Alaska), Inc. (BPXA) requested authorization to conduct a pilot miscible injection (MI) project in Borealis Oil Pool (BOP) Wells V-100, L-105 and L-108. The Commission approved BOP water injection for enhanced recovery purposes by Conservation Order 471 (CO 471), dated May 29, 2002 and Area Injection Order (AIO 24) dated May 29, 2002. Permission to conduct a pilot miscible injection project in the BOP can be administratively approved provided the pilot does not cause waste, jeopardize correlative rights, is based on sound engineering and geoscience principles and will not result in an increased risk of fluid movement into freshwater.

You have advised us that MI injection is planned to start late-June in the subject wells and continue no later than October 1, 2004. Pilot miscible injection for 10-12 weeks is proposed to gain information on the range of injection rates to expect in the BOP and Borealis MI distribution system capacity.

The reservoir pressure in the pilot area is above the BOP minimum miscibility pressure (MMP) of 2150 psi. Average reservoir pressure in the BOP is approximately 2832 psi. Pilot operations for short-term injection may provide valuable information for later long term expansion of the area under MI flood, potentially enhancing recovery.

The Commission hereby approves BPXAs request to inject miscible gas into BOP Wells V-100, L-105 and L-108 subject to the conditions, limitations, and requirements set out below and statewide requirements under 20 AAC 25 (to the extent not otherwise superseded by AIO 24 and Conservation Order 471).

DONE at Anchorage, Alaska and dated June 29, 2004.

John K. Norman, Chair
Commissioner
